Engineering DesignOur Team Leader's favorite quote:
"Just get it done!"Why we think we should win:
There are multiple reasons why our team should win the Rube Goldberg contest. We put in a lot of time, effort, and thought into this project. We faced many trial and errors over the past few weeks. However, we have come up with a Rube Goldberg machine that works well and uses the required number of steps to do the required action. Suggestion for next year's challenge:
1) Plant a seed
2) Poor milk into a cereal bowl
3) Knock down 10 bowling pins
4) Open a book
5) Crack an egg into a pan
6) Cut a loaf of bread
7) Peel a banana
8) Dial a phone
9) Open a drawer
10) Hit a golf ball into a hole
